The article discusses the development and advantages of difluoromethane (R-32) as a refrigerant in Pakistan. R-32 is more environmentally friendly and energy-efficient compared to older refrigerants like R22 and R410A. However, there have been incidents of burning and accidents associated with R-32 in Pakistan. The article suggests steps to ensure safety and maximize the benefits of R-32, including understanding the root cause of the issue, educating consumers, proper installation by certified professionals, enforcing strict standards, and improving the construction and materials used in R-32 units. The adoption of R-32 in Pakistan is seen as necessary for aligning with global sustainability goals, but responsible practices and continued research and development are crucial for a greener and more sustainable refrigeration industry.
